Additional specifications and description
Differential pressure, air volume flow or air velocity?
This sensor measures differential pressure [Pa] in two different locations simultaneously. Based on the measurements, air volume flow [m³/hr] or air velocity [m/s] can be calculated. To calculate air volume flow based on the K-factor of the fan, use the optional connection set type PSET-PVC-200 or PSET-QF-200. This connection set can also be used to measure differential pressure. To calculate air volume flow based on the duct cross section [cm²] or air velocity [m/s], use the optional connection set type PSET-PTS-200 or PSET-PTL-200.
How does it work?
This sensor has two analogue outputs. Each output transmits the measured differential pressure, air volume flow or air velocity proportionally. The default range of this sensor is 0 to 1.000 Pa. By default, each output transmits 0 V at 0 Pa and 10 V at 1.000 Pa. This range, the output types and all other settings can be adjusted via Modbus RTU.
Heat Recuperation Unit
This sensor measures air volume flow in two different locations simultaneously. It can be used to monitor the supplied and extracted air volume in ventilation systems or Heat Recuparation Units (HRU).
Easy to connect
The supply voltage, both outputs and Modbus RTU communication can be connected via the screw clamp terminal block. This sensor can be supplied with 24 VDC or with 24 VAC. It is intended for 3-wire connection. The ground of the output (GND) is internally connected to the ground of the supply voltage (V-). Make sure not to connect this common ground to other devices that are powered by a DC voltage.
High quality
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is heat resistant, very tough and offers good protection against impacts. The pressure connection nozzles are made from Aluminium. The sensor enclosure offers an IP65 protection against ingress of dirt and water. This sensor can be wall-mounted.
